Title: Image processing unit
Inventor: HOSONO TAMOTSU
IPC: G06T1/00
Filed: 1995-08-02
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous correction of even dirt due to dust when a white level reference face gets dirt due to dust or the like in the case of conducting MTF correction. SOLUTION: A read image signal processing section 1 applying various processing to image data read by a scanner 2 is provided with a white reference face peak level latch circuit 7 and an MTF correction constant setting circuit 9. The white reference face peak level latch circuit 7 latches a peak level when a white board is read prior to reading an original. The MTF correction constant setting circuit 9 sets a constant for MTF correction calculation in response to the peak level of the white reference face latched by the white reference face peak level latch circuit 7 in the case of reaching each original so as to prevent accurate MTF correction from being unable because of reflection into the processing by the dirty white level board.

Title: Scroll compressor
Inventor: NAKAMURA TOSHIYUKI
IPC: F04C29/04
Filed: 1981-12-28
Abstract: PURPOSE:To prevent seizure of sliding parts of a scroll compressor, by cooling a motor by suction gas, and preventing oil rise during operation of the compressor by separating lubricating oil effectively in the body of the compressor. CONSTITUTION:Suction gas is passed through a suction pipe 12 and carried to an upper portion in a motor chamber defined by a frame 5 and a motor stator 8. Then, the gas is carried from the upper portion to the lower portion of the motor through an air gap 14. Here, oil leaked from sliding portions 2a, 3b, 3c and 2b flows downward together with the suction gas. After passing through the motor, the suction gas is carried into a compression chamber 4 via a connecting passage 17, a suction port 15 and an inlet portion 4a. On the other hand, oil is separated from the gas by the difference of weight when the direction of the gas flow is reversed at the lower portion of the motor, and the coil thus separated from the gas is collected in an oil sump 16.

Title: Circuit system
Inventor: HASHIMOTO YOSHITERU
IPC: H03G5/24
Filed: 1982-12-09
Abstract: PURPOSE:To increase the reception band width as the frequency changing speed increases in a channel selection mode by changing automatically the reception band width in response to the frequency changing ratio when the tuning frequency is controlled. CONSTITUTION:The diagram shows a circuit which switches filters having different pass band widths with an electronic switch. If the comparison voltage is set as Ea<Eb, a comparator 54a is first inverted to set the output level at H when the control speed and Ep increase. Therefore the output of an inverter is set at L, and electronic switches 52c and 53c of a narrow BPF51c are cut off. The Ep increases more when the control speed is further increased. Then the input of an exclusive OR is set at L level by HH after a comparator 54b is inverted. Thus electronic switches 52b and 53b of an intermediate band filter 51b are also cut off. Instead, the control circuit of a wide BPF51a is set at H, and therefore electronic switches 52a and 53a conduct to perform a wide band action.

Abstract: PURPOSE: To switch an antenna in accordance with the transition of a level and to prevent the occurance of unnecessary antenna switching by switching an antenna whose received signal level is lower than a threshold to an antenna with a received signal level higher than the threshold, and when the average level of a received signal is lower than a prescribed fixed value, inhibiting antenna switching. CONSTITUTION: The level of a received signal received by an antenna A1 or B2 is averaged by an average value calculating part 5 to find out an average value. A threshold calculating part 7 finds out a threshold by multiplying the received signal level by a fixed value and the result is compared with a current received signal level, by a comparator 8 and when the received signal level is larger than the threshold, the current antenna is held as it is. When the level is lower than the threshold, the antenna is switched. The received signal level is compared with a received signal level minimum reference value by a comparator 9. When the level is lower than the minimum reference value, a control switch 11 is turned off and the current antenna is fixed.

Abstract: PURPOSE:To improve an SN ratio, to eliminate the need for a time-base compressing and expanding process and to reduce the cost of a device by imposing FM modulation on a video signal which has a positive-polarity synchronizing signal and recording a horizontal burst signal and a pilot signal on a frequency multiplex basis together with the FM-modulated video signal. CONSTITUTION:An MUSE signal from an input terminal 1 is applied to an FM modulator 2 and a synchronous separating circuit 3, which detects the positive-polarity synchronizing signal and separates the horizontal synchronizing signal. This signal is applied to a modulator 2 and also applied to a burst signal generator 4 to generates a horizontal burst signal. The level variation of this horizontal burst signal is matched with the gradient of the positive-polarity synchronizing signal of the MUSE signal. The FM signal from the modulator 2, on the other hand, is sent to an adder 7 through an HPF 5 and frequency-multiplexed by the adder 7 with the horizontal burst signal and the pilot signal from a pilot generator 6. This multiplex signal is applied to a head 9 through a recording amplifier 8 and recorded on a tape 10. Consequently, the signals are recorded with a large frequency shift and the SN ratio is improved. Further, no time-base compression is performed, so any expanding process is not required.
